In 1940, Geller was ranked No. 5 in the USA in the junior (15 and under) category. Then he chopped off his right thumb in a lawn-mowing accident. Jack redesigned his game so that he became effectively ambidextrous; the forehand was the only shot he could hit naturally without the use of his thumb. Today, Dr. Geller is a distinguished endocrinologist in California.
Geller was a star player at Yale (class of 1948), where he played with fellow Jew Irvin Dorfman. Jack was a top 30 player (No. 29) in the U.S. in 1950.
